    Quick question - How do you determine the direction of flow of water through a radiator? I'm fitting a new radiator upstairs and the instructions say that the bleed valve must be diagonally opposite the flow.

    Any help would be much appreciated :lease:

    In my experience, it is usually marked either on the boiler itself, or in the instructions for said boiler... either way, unless the plumber who installed it in the first place marked the pipes, you will be following pipes...:)

    If you've got an existing radiator there (or capped off pipework), fire up the system and feel the pipes - the inlet will be getting warm, the outlet will remain cold (or much cooler)
